Thanks guys your comments are appreciated,   added some detail to the two handed doors, and thought I'd make a few more fittings to reproduce.

We're watching and learning from your example Joe - and those doors are looking good.  O0

Very nice doors as already said Joe. Will the mould for the fairleads/mooring bits be a two part mould
or will the silicon take the undercut Joe. (still trying to learn)

Hi Colin, I had already decided to buy in the open fairleads in metal, it may be possible for me to make and mould them but they are quite thin at the top opening I think they would be very prone to breakage in resin.

Coming along nicely Joe. I am going to order a casting kit from sylmasta today, I have got to start making my own moulds, still trying to fathom it all out. Great work as usual from you. Cheers Joe.

Good for you Phil, I'm sure you will find it fun to do, just start with easy things like doors etc. Then use your imagination, I was charged over 200 for a "set" of 1:96 fittings by a certain supplier for my Coventry and when they came I'm dammed if I could see they were worth it, I only used the Scott domes and armaments, I thought then I could do better than that and it works out cheaper. :-))

Good point Joe, you will have to start making some of the metal fittings next.
I have to agree your fittings appear a lot better than the ones sitting in a couple of
kit boxes in my shed. Still live and learn.
I am learning a lot from your builds and many of the others on the forum, Please keep the posts coming.
Thanks

Thanks Colin, if my build logs help anyone I'm only too pleased, the main reason I do a build log is so I have a record of each build I do, if I just did a log at home I'd most likely forget to take regular photos etc. By doing one on Mayhem I'm a bit more dedicated plus I'm on here regularly and get inspiration from the excellent modellers on here. ;)

Update on moulding the bollards, the moulding came out ok and by fitting the bases separate I'm able to do all eight bollards from one mould even if they are handed like the forward ones.

After talking about the fairleads I got to thinking maybe I'll try and make one, so I fettled one out of two pieces of styrene profile glued together, well I thought it came out ok, then I thought about the moulding of it, to make a mould of it standing upright would need to be a split mould due to the nature of the hole, I felt this was a bit complicated for such a small fitting, of course I could fettle all eight of them but I doubted I could get them all identical,  it then dawned on me it could be moulded laid on it's side, which is what I did, and the first one has just been done, after sanding off the excess resin, I think I have some passable fairleads that are actually stronger than I had thought.

Very good fairleads Joe. You will soon have enough to start a small business  ;)

Hullo Joe.....watching the full build...& whilst I understand you are faithfully constructing components as per the plan.....I had to think twice of how best to describe the bollards as designed  >>:-(

Two round pegs in a bigger rectangle and all mounted on a bit bigger parallelogram  O0 ....

We must consider all of the forces are both in tension and shear on the inboard four securing bolt/rivets .....Derek

Not wishing to be a "Rivet counter" Derek, I assumed that the 4 rivets are just meant to give an impression of the means of fixing the bollards not the literal number employed or am I being a dumb a*s, as they often are on model loco engines. Do you suggest that 4 is the magic number lol if so I am surprised all the bollards were not lost in the wet stuff  :-))

Colin.....I would have thought even with draftsman's licence   %) ...the number of bolts or fasteners on the sub base to the deck on a singular item such as this would have been prototypical [in number]

There are no actual bolts indicated between the bollard rectangular base and the lower parallelogram sub base, to this interface may have been welded

Bollards like these really only hold a vessel to or against a wharf...... whereas the fairleads are often subjected to far greater forces .....

I too was not counting rivets or bolts...was just the shape of the sub base that appeared odd...........I do however enjoy all of the build threads by Joe :-)).....Derek

I wasn't sure about the bollard bases myself as I only had the plans to go by, but seeing your photo has given me a lot more confidence in plans, I guess it's one of the photos from your tour over Quorn, the last time I was in the dockyard I went down to see if I could get on Brocklesby but she was all locked up maybe they were on weekend leave, that type of photo is invaluable to aid a build thanks Dave.  :-))

I guess Daves pic says it all then Derek  O0
It does seem quiet a small number of rivets/bolts but I guess the senior design engineer must have been happy the
figures for the tensile strength of the mounting method.
I am glad that your confidence in the plans is improved Joe, which plans are you using? I must admit to having doubts sometimes using drawings by other draughtsmen.
Like Derek I too really like following your builds Joe most entertaining and I learn stuff as well. Keep the posts coming sir  :-))

Thanks Colin, yes I'll keep posting as long as there's some interest, the plans are Fleetscale, very nice plans actually, four large sheets with most of the fittings detailed separately and a lot of views even below the well deck, the plans are for HMS Cottismore that was converted to a patrol vessel in 1997 and sold to Lithuania in 2008, but although there were slight differences between the Hunt Class fleet as far as I have been able to research Cottismore and Brocklesby were identical so should be fairly correct with a bit of licence of course.  %%

Looking forward to your next installment Joe :-)) I wonder what the black oblong on the deck by the bolards is/was?

Hello Joe,

I like your build and was surprised to see that you make mouldings and castings. I order some silicone and resin too but I have a question. Do you use vacuum to make the moulds?

Kind regards, Kees

Hi Kees,  no you don't need vacuum you just have to be careful to avoid air bubbles, once you have made the fitting and glued it in a "box" pour the silicon in slowly from one corner this pushes the air out of the mould, the resin, I usually pour a small amount in and move it around with a cocktail stick or similar to disperse any air bubbles then fill the mould, try not to over fill or you will have more to sand off when it's set, hope this helps.  :-))
